I am going to pass on my dealers suggest to purchase their 10ft AQ Redwood cable pr., since they are much too long for my purpose. My speakers spread 'center to center' is 7.5ft, so space available give or take is just 6.5 ft. (78") to place MC611 mono amps and rack with preamp C2700, Niagara 5000, HIFI Rose 150, MEN220 room adjustment and MCD600 or MCD12000 SACD/CD player. So i suspect I only need 1m or 1.5 m speaker cable with a single 4 level rack will be tight. I may have to spread the speaker a foot more. They also want to replace all the equipment power cords with AQ products.
